ALSA: add /sys/class/sound/card#/id (r/w) and card#/number (r/o) files

For udev, we need a way to rename soundcard names. The soundcard numbers
(indexes) are hardwired but we have a text identification which can be
changed at run-time. The ALSA user space tools already allow using of
this text identification.
